Of key interest is a new Mega Evolution for legendary psychic-Pokémon Mewtwo, reportedly known as Mega Mewtwo X. This is apparently a Psychic and Fighting-type evolution with the ability Steadfast, in-game screenshots seeing the evolved form throwing a rather weighty kick at an opponent.

We can expect The Pokémon Company International to make an official announcement regarding these additions within the coming days.
